Hi guys. I would like kibana to use my timestamp which are in the logfiles fed from logstash.

My logstash conf looks like:

filter {  
if [type] == "dibslog" {  
grok {  
match =\> { "message" =\> "%{DIBSLOG}" }  
remove\_field =\> ["message"]  
}  
mutate {  
add\_field =\> { "syslogtimestamp" =\> "%{month} %{day} %{time}" }  
}  
geoip {  
source =\> "clientip"  
target =\> "geoip"  
database =\> "/etc/logstash/GeoLiteCity.dat"  
add\_field =\> ["[geoip][coordinates]", "%{[geoip][longitude]}" ]  
add\_field =\> ["[geoip][coordinates]", "%{[geoip][latitude]}" ]  
}  
mutate {  
remove\_field =\> ["month","day","time","host","offset","file"]  
}  
date {  
match =\> ["syslogtimestamp", "MMM dd HH:mm:ss", "MMM d HH:mm:ss"]  
}  
}  
}

And I actually have the field in Kibana with my syslogtimestamp - example: "Sep 13 13:01:07".

But during kibana's index pattern configuration, Kibana does not show syslogtimestamp on the list of time-fields...

I have added syslogtimestamp to the list of metaFields, but that didn't help.

What does the mapping for that field look like in ES?

It is a string, unfortunately...

Okay, it is actually working. I have just misunderstood how. It actually updates a different field, @timestamp, which render my own, syslogtimestamp, useless. Fine as it is.
